Studying breast cancer biology at first diagnosis and recurrence
Part of Cancer, Skin clinical trials.
This study looks at how the biology of breast cancer might change when it comes back (recurrence) after initial treatment. By comparing samples from the first diagnosis and the recurrence, doctors hope to better understand how to treat future recurrences.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You are 18 years or older and have been diagnosed with breast cancer.
- Your breast cancer came back (recurred) after you finished your first round of treatment (like surgery, chemo, or radiation).
- A biopsy (a small tissue sample) was taken from the spot where the cancer returned, and the lab checked its biology (like hormone receptors).
- You did not have cancer that spread to other parts of the body (distant metastasis) at the time you were first diagnosed.
- You have not been diagnosed with a second, different type of cancer.

This study collects tissue samples and health information from people with breast cancer that has spread or come back. It aims to help researchers learn more about the disease and may lead to better treatments.
This study follows people who have had breast cancer come back in the same area after surgery. It looks at how well re-treatment works and helps doctors understand how to manage this type of recurrence.
This trial is for people who have had breast cancer treatment (surgery and radiation) and are now being monitored for any return of the cancer in the breast or nearby lymph nodes. It looks at how often cancer comes back in the same area and what factors might affect that.
This study looks at people with advanced breast cancer to better understand recurrence by using information from recent scans. It may help researchers improve how advanced disease is assessed and followed over time.
This trial checks whether specific “surveillance” markers (measured from blood and bone marrow) can help predict if breast cancer comes back after standard treatments. It may help doctors monitor you more accurately and earlier if recurrence risk is high.
This trial looks at how certain proteins (ER, PR, and HER2/neu) on breast cancer cells change when the cancer comes back in the same spot. Knowing this could help doctors choose the best treatment for your recurrence.
